You are probably suffering from what Dermatologist call urticaria. Common causes are food allergy, infection or drugs taken for some condition. It presents with itching resulting in formation of red rashes which we call hives or wheals. Although in most cases cause remains unknown in spite of a thorough search. It can be treated with medicines so that you do not get any new hives. The treatment should be prolonged until it resolves which usually takes 1 to 6 months. Please call me and visit my clinic or contact me through online consult option for further details and treatment..

Without examination of the skin condition and knowing the extent of involvement.. along with this more information on ongoing medication or history of previous/current skin/systemic illness it is not possible to comment on the treatment that would suit you best. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. Hope this is helpful.
